WALL FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 769,656, datedSeptember 6, 1904.

Application filed August 10, 1903.

To (all 1071/0711, it ntnq concern.-

Be it known that I, FRANK E. KIDDER, a citizen of the United States,residing at Denver, in the county of Denver and State of Colorado, haveinvented certain new and useful Improvements in \Valls for Buildings,(Case C;) and 1 do declare the following to be a full, clear, and exactdescription of my invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanyingdrawings, forming a part of this specification, inwhich similar letters of reference indicate corresponding parts in allthe figures.

My invention relates to a class of walls constructed of blocks made ormolded from any suitable material or composition.

The objects of my invention are to provide a wall that will have thestrength and rigidity of solid stone, yet one that can be constructed ata less cost.

The drawings will assist in fully comprehending the nature and objectsof my invention, in which-- Figure l is a perspective view of the blockused in my wall. Fig. 2 is a view of two courses of the blocks as laidin the wall. Fig. 3 is a perspective view of a section of a wallconstructed of two courses of blocks.

in making a further and detailed explanation of my invention I refer tothe main body portion of the block, as designated by the letter A. Ithas two laterally-extending projections, (indicated by r and A Theseprojections are preferably equal distances from the ends of the mainportion of the block, and the distance between them is double thedistance from the end of the main part of the block to said projections.This construction is adapted to facilitate bonding the blocks in thewall. The wall is built of two courses of blocks, as illustrated inFigs. 2 and 3 of the drawings. It is also made manifest by consultingthese figures that perfect bonds are formed by laying the blocks so thatthey break joints in the courses as they are laid upon each other. Theblocks may be laid in any suitable cement or mortar and are preferablyarranged with one of the pro ections of each block engaging the bodyportion of the opposite or mating block and the second pro-SerialN0.169,0Z2.

jection engaging the inner face of said block at a point near the endthereof, thereby forming a seat on each side of the wall for the end ofthe adjacent block. It is obvious that the wall will be impervious todampness, as the air-ducts will preventpenetration of moisture.

I desire to cover by Letters Patent the wall built from blocks of theprinciple shown and described.

'hat 1 claim as my invention is 1. A hollow wall composed of a pluralityof blocks each comprising a body portion having intermediatelaterally-extending projections, said blocks being laid side by side andarranged in superposed courses with one of the projections of each blockengaging the body portion of the opposite or mating block at a pointintermediate the lateral projections thereof and the second projectionengaging the inner face of said mating block, at a point near the end ofsaid block thereby forming a seat on each side of the wall for theterminal portion of the adjacent block and defining air spaces or Huesof substantially uniform width between the several projections.

2. A hollow wall composed of a plurality of blocks each comprising abody portion having intermediate laterally-extemling projections spacedso that the distance between them is double the distance from the end ofthe body portion to said projections, said blocks being laid side byside and arranged in superposed courses with one of the projections ofeach block engaging the body portion of the opposite or mating block ata point intermediate the lateral projections thereof and the secondprojection engaging the inner face of said mating block at a point nearthe end of said block thereby forming a seat on each side of the wallfor the terminal portion of the adjacent block and defining air spacesor flues of substantially uniform width between the several projections.

In testimony that I claim the foregoing as my own lv hereunto subscribemy name in the presence of two witnesses.

FRANK E. KIDDER.
